摘要
目的:优选超声提取制何首乌中多糖的最佳工艺。方法:采用正交设计的方法,考察提取时间、提取温度、料液比、提取次数对制何首乌多糖得率的影响,优选出最佳的超声提取工艺,并与热水浸提法进行比较。结果:超声提取的最佳条件为用25倍的水,70℃超声提取,提取时间50 min,提取2次,多糖的得率20.04%,与热水浸提法相比提取时间明显减少。结论:该方法快速、高效、可行。
Objective: To establish the optimal ultrasonic extraction technology of polysaccharides from Polygoni Multiflori Radix Praeparata.Method:Extraction time,extraction times,the ratio of sample to solution,and extraction temperature were set as index for orthogonal test,and Compared with hot water extraction method.Result:The optimal ultrasonic extraction Process of polysaccharides from Polygoni Multiflori Radix Praeparata was extracted 2 times for 50 min each time at 70 ℃ with the ratio of dry material to water was 1∶25,the yield of polysaccharides is 20.04%.Compared with water extraction,the extraction time reduced obviously.Conclusion:The optimum ultrasonic extraction process for polysaccharides is rapid,efficient and feasible.
